3. on the whole template resolution issue, is the current recommendation to make templates at 1080P still the "right" one? Most of my effects are CPU based, and I don't like the idea of having the source footage always uprezzed to 1080P and processed at that size, if the source footage is only 720P or even wide DV. Adding multiple templates at different common resolutions is likely to confuse users. Having my effects take twice as long to render as they should is likely to annoy them. And then they'll rant that my effects are "slow", which annoys me.
Thoughts?
This is another area where we have some bugs filed, but more would help. I'll also see if there's anything I'm missing about this, as I don't know everything about the template system.
In case as you guys used to have some decent automatic QA internally for Shake at least...
A simple test procedure Apple could use in internal QA is something like make an uncompress movie (with 0.91 PAR) that is just
alternate 1,0,1,0 for pixel values (ON/OFF) repeated at all frames... (you could maybe if this could be more then 8 bit do
something that looks like a bit like a bayer mosaic ant set the alternatively R then G then B ON value to something not 1.0 to allow
you to catch 8 bit in pixel path, and gamma or pixel order out of wack).
make a plugin that reads a frame at another time (A), reads a frame from that movie copy using the clip well (B) , and reads the
main input (C),
plugin loops through pixels and does a diff of A to B (if pixel is different r=1,else 0), and B to C (if pixel is different g=1,else
0), and C to A (if pixel is different b=1,else 0).
For more complete case replace last diff by a procedural one that redraws the mosaic and where ON level is equal to the float value
level that is equivalent to the rounded value on either 0-1023 or 0-4095 levels scale used to make reference test pattern movie source.
Make a template at 1080p square pixel with that fabulous effect
load SD res movie and apply template in FCP-X...
repeat software and hardware.
If you don't get a constant black image, bug!
Add test for checking OSC location is equal to pixel value (requires a different movie) and this tests as well sub-sampling location
Add test for matching param keyframe value and get frame at time value
Add test for testing colorspace conversion roundtrips...
Add sound effects for poor testers that checks all this for you in one test
etc
